Abstract: 

    Repeat digital groundbased photos are taken once to twice a year to document plant litter and


    soil deposition or removal by wind and water transport on ten microplots located on each of the
    8 plots at each of the Aeolian, Dona Ana, and Gravelly Ridges sites. Five photos are taken of
    each microplot: One overhead (from directly over the microplot) and 4 lateral views at ground
    level of the microplot from each cardinal direction.

   Digital filenames are fully descriptive of the site, plot, microplot, photo view, and date taken.
   Photo filename structure:
      Example: A1-1E_20101109_IMG_1006368.jpg
               12-34_55556677_88888888888.jpg
         Where 1 = site: A=Aeolian: D=Dona Ana; G=Gravelly Ridges
               2 = plot (1-8)
               3 = microplot (1-10)
               4= photo view (O=overview; E=looking east; N=looking north; S=looking south; W=looking west
               5-6-7 = year month day of photo
               8 = original image number assigned by camera

    Plot Setup
       o There are 3 sites:  Dona Ana, Aeolian, and Gravelly Ridges.  Each site has 4 control
         plots and 4 treatment plots.  In addition to each 8m x 8m plot, two buffer plots of the
         same size are located at each end of the plot- one upwind/upslope and one downwind/down
         slope. Only the central plot has the photo microplots.
    10 microplots (microplots with Conmods are 50cm diameter x 20cm tall) were initially selected
    at random to become the permanent set of microplots used for the repeat annual photos.

   Digital filenames are fully descriptive of the site, plot, microplot, photo view, and date taken.

         Where 1 = site: A=Aeolian: D=Dona Ana; G=Gravelly Ridges
               2 = plot (1-8)
               3 = microplot (1-10)
               4= photo view (O=overview; E=looking east; N=looking north; S=looking south; W=looking west
               5-6-7 = year month day of photo
               8 = original image number assigned by camera

Additional information: 

   There are 3 site locations:  Aeolian, Dona Ana, Gravelly Ridges.  The UTM coordinates
   below are approximate, and based on the UAV photo coverage we have for each site.
   Precise GPS coordinates are available.

   Dona Ana.  These are located north of Herrick's SD97C (Surface Disturbance) exclosure,
   which is north of the Dona Ana exclosure, which is in the SW corner of JER Pasture 6..
